Title: Improvements in shaft furnaces
IPC: F23H3/02
Filed: 1955-12-02
Abstract: 789,912. Solid fuel-fired and liquid and gaseous fuel-fired combustion apparatus. VORKAUF, H. Dec. 2, 1955 [Dec. 16, 1954], No. 34547/55. Class 51 (1). A furnace of the type comprising a combustion shaft surmounted by a solid fuel storage hopper is adapted for oil or gas firing by fitting a burner or burners in one wall of the hopper. In the water-tube boiler of Fig. 1, which comprises a combustion shaft 1, topped by a hopper 2 which is filled from above through an opening 7, oil fuel firing is made possible by the provision of a burner 3. The shaft 1 comprises spaced water-cooled tubes 4, 5 such that combustion air flows horizontally and in order to efficiently burn oil the hopper 2, which is formed of water-cooled tubes, has the cooling effect of its bottom inclined wall nullified by a refractory slab. Water tubes 6 cool the side walls of both hopper 2 and shaft 1. In the boiler shown in Fig. 2, an oil burner 3 is arranged in the hopper roof, the air for combustion being preheated by being passed through an air jacket 18 used for cooling the refractory 8 surrounding the burner. In the boiler of Fig. 3 oil and solid fuel may be burnt simultaneously the hopper 2 being divided into chambers 10, 11 by a partition 9 for this purpose. An opening 12 through which combustion products emanating from the burner 3 pass to the boiler is closed by a slide 15 when oil firing is not in progress or when the chamber 11 is used to store solid fuel. In the simultaneously oil and solid fuel-fired boiler of Fig. 4 the combustion gases emanating from the burner 3 have to pass through the column of fuel in the shaft 1, thereby accelerating the ignition of fresh solid fuel.

Abstract: 1277967 Transistor switching circuits WEST. ERN ELECTRIC CO Inc 11 July 1969 [12 July-1968] 35000/69 Heading H3T [Also in Division H1] Fig. 4 shows a switching circuit which uses "vertical" JUGFETS integrated with bipolar transistors. The circuit has two bipolars 53A, 54A driven in parallel by another bipolar 52A. To prevent current hogging in the parallel bipolar transistors the base circuit of each of them includes a JUGFET 56A and 57A acting as a current limiter. As shown the collector current of the driver transistor 52A is limited by a further JUGFET 73 though in a variant the JUGFET is replaced by a resistor. Other circuit uses for the JUGFETS are suggested. A "vertical" JUGFET according to the invention is carried by a 5 ohm-cm. P-type silicon substrate (32), the conduction channel of the transistor being that part of the 1 ohm-cm. N- type epitaxial layer enclosed by the boron-doped hollow-cylindrical diffused zone (37) which acts as the gate. An antimony-doped sub-layer (33) acts as a source/drain electrode and is connected to the surface by a high conductivity diffused portion (41). The other source/drain contact is provided on a surface zone (38) heavily doped with phosphorus. In the embodiment shown the N<SP>+</SP> sub-layer (33) also acts as the collector contact for an NPN transistor (40, 39, 34) contained in the same pocket as the JUGFET within diffused P<SP>+</SP> isolation wall (35). Several JUGFETs and bipolar transistors may be provided in one pocket, as desired.

Title: Improvements in babbitted bearings
IPC: F16C17/06
Filed: 1922-12-30
Abstract: 193,381. Schein, A. E. Feb. 20, 1922, [Convention date]. Brasses; spring supports; cylindrical bearings; vehicle-axle bearings; thrust bearings.- Bearings are lined with a material of low modulus of elasticity such as Babbitt metal, the thickness of which is proportioned so that a wedgeshape film of oil will be produced and maintained between the bearing surfaces. As shown in Fig. 1, applied to a thrust-bearing, a collar 2 on a vertical shaft bears on a lining 4 of Babbitt metal carried on a non-rotatable block 5 which is supported resiliently by springs 7. The block 5, Fig. 7, has a saw-like, upper face 9 so that the thickness of the. metal fitted thereon diminishes in the direction of rotation of the shaft. The lining may be in one sheet or composed of a number of blocks and the thicker parts of the lining may be tapered as at 14<1> and provided with radial grooves 14. When the shaft rotates in the direction of the arrow 15, a wedge-shape film of oil is drawn between the Babbitt metal and the shaft collar 2 due to the radial compression of the metal at any point being proportional to its thickness. Lubricant, circulated by a pump driven from the shaft 8, passes through a passage 53 and a central passage 54 into the grooves 14 and to the bearing surfaces. It. then collects into an annular space 55 surrounded by a ring 56 with baffles 57, passes over the edge of the ring 56 into an, annular space 57<1> and through the opening 58 to the pump. The springs 7 may be replaced bv a disc of elastic material such as cork or felt. As applied to a journal bearing, especially for gyroscopic rotors, the lining of Babbitt metal may be in four quadrants, the centre of curvature of the bearing surface of each quadrant being slightly to one side of the axis of the shaft so that the shaft may bear on a 90‹ sector no matter in what direction the load is applied. Axial passages formed between the blocks for the passage of lubricant preferably have the central portion offset. As applied to an axle box, Fig. 9, blocks 44, 45, are fitted in a brass 40 so that their thickness diminishes towards the top of the shaft. The brass 40 has members 41 normally clear of the shaft which are brought into action in resisting the lateral thrust of the brake shoes.

The error signal is amplified and then applied to the coil 18 of an eddy current brake which is coupled to the tape. This enables the head 13 to register correctly with bands recorded on the tape despite alterations in the length of the tape due to changing atmospheric conditions.

Abstract: 1324392 Zeolitic molecular sieve agglomerates UNION CARBIDE CORP 23 July 1970 [24 July 1969] 35661/70 Heading C1A Hardened agglomerates of zeolitic molecular sieve crystals are prepared by forming an initial agglomerate comprising compacted molecular sieve crystals, applying a uniform thin continuous coating of boehmite alumina particles to the agglomerate, impregnating the alumina coated agglomerate with an aqueous potassium silicate solution (2-4 wt. per cent solids) and then firing the impregnated agglomerate at a temperature (e.g. 1050‹ to 1220‹ F.) sufficient to set and harden the silicate. The boehmite alumina particles used have been thermally deactivated at 250‹ to 350‹ C. for from 0À75 to 1À5 hours, may be less than 300 U.S. mesh in particle size, and form a coating of thickness 1 micron to 0À003 inch. The potassium silicate solution may have a K 2 O : SiO 2  ratio by weight of 0À477 to 0À40 : 1, and from 0À03 to 0À07 pounds of solution solid may be used per pound of agglomerate. Colloidal silica in suspension may also be present in the silicate solution. The agglomerates may be bonded with 5-35 wt. per cent clay (e.g. attapulgite, kaolin, sepiolite, polygorskite, plastic ball clays, bentonite, montmorillonite, illite and chlorite). The agglomerates may be dried between impregnation and firing. In Example 1, Type 3A molecular sieve crystals (80 pts. by weight anhydrous) and attapulgus clay (20 pts. by weight anhy- .drous) were dry blended, water (21 parts) was then added, and spherical bodies were formed by tumbling. 2% By weight boehmite alumina (particle size = 44 microns), previously heated at 300‹ C. for l hour in air, was tumbled with the spherical agglomerates. The coated agglomerates were soaked for 6 hours at 70‹ F. in aqueous potassium silicate (solids content = 2À9%), dried, and fired at 625‹ C. for 30 minutes.
